Precaution
1Let the desingner of pneumatic system or rule tester to determine if this direction control valve
is suitable or not.
2The product must be operated by the person who has professional knowledge and practical
experience.
3Please conrm product specications before use. Do not use input signal exceeding specications.
This product could malfunction re if input signal exceeding the working range is applied.
4If an abnormality occurs during operation, immediately turn off the power and air pressure and
stop using it.
5This product is adjusted for each specication at the time of shipment from the factory.
Disassemble and reformation are prohibited, as this way might lead to malfunction.
WARNING
1Avoid using this regulator where it will be subject to direct sunlight, water or oil, etc.
2Use in place where the temperature changes drasticlly or at high humidity may cause damage
due to dew condensation in the product.
3If supply pressure to this product is interrupted while the power is still on, the inner solenoid
valve will continue to operate and a humming noise may be generated. Since the life of the
product may be shortened, shut off the power supply also when supply pressure is shut off.
4If electric power is shut off while pressure is being applied, the output pressure will be retained.
However, this output pressure is held only temporarily and is guaranteed.
To ensure safe operation, please read this service manual carefully before use. When desingning and
manufacturing equipment using Mindman products, the manufacturer isobligated to ensure that the
safety of the mechanism, pneumatic conrtol circuit and/or air control circuit and the system that runs
the electrical controls are secured.
Explanation of label
Observe the warnings and cautions on the following pages to prevent accidents. These instructions
indicate the level of potential hazard by labels of "WARNING" or "CAUTION".Note that some items
indicated with "CAUTION" may lead to serious results depending on the conditions. All items
contain important information and must be observed.
A dangerous situation may occur if handling is mistaken, leading to fatal or serious injuries.
CAUTION
A dangerous situation may occur if handling is mistaken, leading to minor injuries or property damage.

Precaution
5The product characteristics are conned to no ow in the pipeline. When air is consumed on
the output side, pressure may become unstable.
6In order to avoid the error caused by noise, please take the following measures:
aSet the line lter on AC power line to remove the power noise.
bKeep the product away from the engine and power line to avoid noise affects.
cInduced charge (like solenoid valve, relay), must prevent them from negative chargge.
dIn order to avoid the effects of power uctuation, please cut off the power before plug
the connector
7The cable plug is four-core wire. Please avoid contact with other wires to avoid product failure.
8Please note that the right angled cable connector does not rotate and is limited to only one
entry direction.
9Use clean compressed air that does not contain corrosive gas. Poor air quality adversely affects
function and life.
10 Do not use a lubricator on the supply side of this product, the lubricated air might cause
malfunction. When lubrication of terminal equipment is necessary, connect a lubricator on the
output side of the equipment and set a check valve.
11 When supplying compressed air for the rst time after connecting pipes, conrm that no air is
leaking from any pipe connections.
12 Tighten pipes with the appropriate torque to prevent air leakage and screw damage. First
tighten the screw by hand to prevent damage to screw threads, then use a tool.
13 For the pneumatic source, use cleaned air from which the solid, water and oil contents were
eliminated sufciently, using an air dryer, lter and oil mist lter. Recommend selecting a
ltration precision of 5µm or less.

Installation instructions
1The 4-Pin port on the right side is the power supply port. Please refer to page 5 for details on
the wiring method.
2The 5-Pin port on the left side is the communication interface. Please refer to page 5 for details
on the wiring method.
3Be aware that excessive bending may cause damage or short circuit, resulting in abnormal
function or re. Be sure to reserve sufcient space for wiring. (The minimum bending radius of
the wire is 70mm)
4When installing L-type bracket and right-angle cables together with the product, pay attention
to whether the wiring space is sufcient.
5Please note that the right-angle cable connector does not rotate and is limited to only one entry
direction.
6Insert/pull out the connector after cutting the power supply.

Wiring method
1Please conrm the product specication and read wiring method carefully before wiring.
2The color of connector pins and cable conductors must be checked when wiring. Check wire
color with handling precaution, since improper wire connection leads to destruction/-failure
and malfunction.
3Do not use power voltage exceeding specications. The product could malfunction or catch re
if voltage exceeding the working range is applied.
4Short-circuiting the load could result in rupture or re.
5The connection between the cable plug and the wire is weak. Excessive bending may shorten
the life of the plug set, causing breakage or damage.
